SLVUBD0A January 2018 – July 2021 TPS563240 , TPS563249
3 Modifications
These evaluation modules are designed to provide access to the features of the TPS563249. Some modifications can be made to this module.
To change the output voltage of the EVMs, it is necessary to change the value of resistor R1. Changing the value of R1 can change the output voltage above 0.60 V. The value of R1 for a specific output voltage can be calculated using Equation 1.
Equation 1. 
Table 3-1 lists the R1 values for some common output voltages. Note that the values given in Table 3-1 are standard values and not the exact value calculated using Table 3-1.
